The DMP80 Series Handheld Dew Point and Temperature Probes are portable devices designed for industrial spot-checking and field calibration. These probes offer high accuracy in dew point and temperature measurements, with a wide measurement range and robustness against contaminants like particulates, water condensation, and chemicals. The sensor ensures fast response times, stability, and excellent performance in dynamic and low dew point applications. They are compatible with the Indigo80 handheld indicator and Insight PC software, and can be used as a working standard for field calibration due to their factory calibration certificates and optional accredited calibration. The probes are suitable for direct process dew point measurement in various temperature and pressure ranges, with a durable design that includes an IP66-rated probe handle for protection against moisture and dust.

Vaisala Oyj Vaisala Oyj is an industrial technology supplier whose business includes moisture, humidity, and gas measurement instruments relevant to hydrogen production and handling. The broader business is instrumentation-oriented, with sensors and analyzers supplied either as stand-alone instruments or embedded into machines, process skids, safety systems, laboratories, and plant automation so operating conditions can be measured and documented. The company’s products typically provide information to a larger control, safety, quality, or test system, making measurement accuracy, response behavior, interfaces, calibration, and environmental suitability part of the integration task. For hydrogen, the company’s actual role is defined by the specific pressure, flow, gas-detection, concentration, quality, temperature, electrical, or other measurement functions described in its portfolio; different suppliers cover different parts of this measurement layer. Its high-accuracy analyzers can monitor water content and dew point in gases and process environments where hydrogen purity and drying are important. Vaisala instrumentation is used for process control, quality assurance, and equipment protection in industrial gas systems. Within the hydrogen value chain, Vaisala Oyj therefore supplies instrumentation, monitoring, or safety technology to OEMs, test organizations, plant integrators, infrastructure developers, and industrial operators handling hydrogen.
